Application filed May15,1912. Serial No. 697,488.

To all whom o may concern Be it known that l, JOHN MCC. Loon- HA'RT, avcitizen of the United States, resid ing at Coraopolis, in the county ofAlle-` State of Pennsylvania, have inv'ented certain new anduscfulImprovemen'ts in Mops, of which the following is a .speciication Myinvention has for its object to proa mop comprising a clamp for the mopmaterial, a handle, and a securing :ferrule or clamp, adapted for easyand quick cons nection and separation, and so designed as to effecteconomy in the cotton `strands or other material used.

The device is illustrated in the accom-- panying drawings, 1n whichFigureA 1 is a view ot the complete 1nop,.

in elevation. Fig. 2 is an enlarged vertical sectional view throughtheiclamping ferrule, handle and clamp. Fig. 3 `is a cross section onthe line 111.111. of Fig. 2. Fig. 4 is'an assembled perspective Viewshowing the wire clamps. Fig. 5 is a view similar to Fig. 2 illustratinga modified construction. Fig. 6 is a vertical section of the fer-ruleused in the construction of Fig. 5 at right angles thereto. Fig. 7 is across section on the line VII. VII. ot' Fig. 5.

The roperative or Working portion of the mop is the head2 consisting ofan assen1- bled mass ot strands of loosely woven cotton or the like.They are collectively held .'at their middle portions in a closelyclamped central head portion by a wire clamp, illustrated in detail inFig. Il. Thus, the clamp is made of a st `and of wire having one or more`coils 8 normally spaced apart at il and having extended securing sidepieces or horns 5, 5, for attachment. 'to the handle 6. In theconstruction shown in the Vprincipal figures `of' the drawing the horns5 terminate ininwandly turned studs 7, 7, adapted to extend intoreceiving sockets 8 at opposite sides olf the handle. rlhe cottonstrands are `passedA diametrically through the spaces 4 and the coils 3are then ,closely drawn together and securedy by hold ing clips orcatches 9. The horns 5 are bent outwardly at their middle portions asindicated at 10, in rounded `form, tor the purpose of makinginterlocking engagement with the ferrule 11. Said errule is tubular inorrnadapted to slidingly embrace the handle 6, and is preferably iaredor langd at the bottom, as at l2, forming a broad solid bearing againsttla` assembled strands at the middle of the mop head. The ferrule isgrooved longitudinally along each opposite inner side, as at 1?). toreceive the h orns 5, and is also apcrturcd through the sides. as at 14,for clearance of the outwardly bowed projections 10. In connect- ,ingthe parts together, the horns 5 of the mop head are tirst passed overthe end of the handle (l and the studs 7 are inserted in sockets 8. Thefcrrule 11 is then lowered over the horns, embracing them at each sideby grooves 13, su'tlicient iorce being exerted to force the bowedprojections 10 inwardly until they spring out through apertures 14.These apertures are so located as toregister with the projections whenthe flange 12 is pressed tightly against the mop head, and by springingout through the apertures the projections act as keys to securely lockthe ferrule in position on the handle, in connection with the insertionof the studs 7 in openings S. It will be understood that the mop as thusconstructed is ready for use. \fVhcn the head 2 is worn out, it isremoved by merely vforcing the ferrllle back, and replacing a new headand clamp and connecting it with thc handle by the ferrule in the mannerdescribed.

lu the construction shown in Figs. 5, G, and 7 the head and clamps aresubstantially Kthe saine in construction except tbatthe horns 5 arestraight and terminate in hooks 7 turned in reverse directions. 'lheferrule 11 is continuous without apertures at the side. but havingcontinuous oppositcly lo` cated longitudinal grooves 13', while theinterior cavity is partly closed at the bottom b v a flange l5 `at aslight distance above the edge cf the outer flaring flange 12. Thehandle (3 is provided with oppositely located pins 1G, 16, and betweenthe inner end of the handle and flange 15 is inserted a coiled spring17. 'lhe parts being assembled` handle t3 is `forced inwardly against`the spring 17 suilieient to lower plus 1G bellow the hooks 7` and thehandle is then turned in tlie'manner of making a bayonet joint andallowed to recede under spring pressure, thus snugly sealing the pinsagainst the hooks 7', as indicated in dotted lilies in Fig. t3.

It will be iniderstood that cach head and its wireclamp is complete as aunit and used with new strands,

strands,

may be collectively discarded when the mop head is Worn out, or theclamp be again if preferred.

'An especial advantage of thef clamp construction is its greatsimplicity 'and ystrength and economy of cotton strands. Thus the bybeing merely laid straightacross between the spirals 3, are of theshortest possible length, utilizing the smallest possible part of themiddle for attachment, and effecting a great savingk in material. Theclamping connection is very tight-and eiicient, The holding action ofthe ferrule is continuously maintained. The parts are rigidly held inposition, and the device as a whole is very etlicient for the objects inview.

It will be understood that the invention may be changed orv varied indiierent detailsor proportions by the skilled mechanic,

but all such changes are contemplated as within the scope of thefollowing claims. What l claim is:

1. A mop head consisting of a securing clamp formed of a continuous wirehaving its endmost portion composed of a plurality Lor/asia ofoverlapping spirally arranged coils and bent outwardly therefrom toprovide extended handle portions, an assemblage 02|? mop strands fixedlyembraced by said coils, and means holding said coils tightly togetherand in lembracing engagement with thel mop strands, subst tially as setforth.

2. A mop head consi ting of a series ofv strands and a securing clamphaving a mfiddle spirally arranged portion engaging the strands,securing clips holding the spiral portion in tight engagement with thestrands, and extended securing horns, sub- JOHN Moo. Lo'cKHAnT.
